A'pplibation'filed October 5, 1912. Seiia-l No. 724,925:-

To ail wltom i'fimay concern Be it known that I, J'osnrir A. GRonBLna citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Iin provements in Bead-Sewing Machines, of which the following is a specification.

My invention relates-to a sewing machine adapted to attach small art-ieies. such as beads, to a fabric.

Heret'ofore in attaching beads to a fabric, generally the beads were first strung upon a thread and their a second thread was Wound spiraliy around the beads and the first thread, the p'iirpose cf the second thread being to retain the beads in proper This simply prepared the string of beads for" attachment; and in this cohdi tion the string of beads Was attached to a fabric by the use of a ziz-zag sewing machine, which latter secured the stringof beads to afabric, by forming stitches over the bead threads.

The object of my present invention isto construct amachine Which will produce a more artistic andpleasing product, reduce and simplify the operation; and ine'rease'the speed of manufacturing as well as reduce the cost thereof. I accomplish these results.

by making the machine for applyingthe beads to the fabric so that the beads may be attached by means of the threadon whichthey are strung, thereby avoiding the use ofthe second or spacing thread shove referred to,-asv Well as the separate sewing thread.

With my invention it is possible to produce a more artistic and pleasingproduct because the beads, or other articles of ornamentation,1nay he stitched upon the fabric by means of the thread upon which they are strung; and they may be secured to the fabric firmly, and in definite positions, so as not to move along their thread. Furthermore no thread engages over the exteriousurf'ace of the beads.

In the present machine stitches are formed with the bead thread, between the several beads. This is accomplished by means of a separator which operates between the thread looper' and the stitchingmember (the needle), to separate or space the beads on their thread, so that they will. be fed in proper relation to the stitching operations; and so that the-stitching member'may form stitches in'the bead thread be tween the several beads. In the full embodiment of my invention the looper which casts the thread around the needle or stitch- ,in g hook also moves the beads and their thread in" such a Way, relatively to the separator or bead feeder. as to cause a periodi: cal separation or feedihg' of the beads, properly timed relatively tothe stitching operations.

in Patent Number 1,04 1,780, dated October 22, 1912, I- show ed and described a machine for sewing beads onto fabrics and the preseiit'inventionrelates to a: device of that character. In the present invention however, the machine isso constructed that the beads chn not only be attached to the fabric in s raight lines,but also'in' the form of curves or angles; That is to'say, the fabricmay be fed in any desired direction While the beads are being attached thereto. For this purpose the separator or head feeder is made'to move in the desired dir'ection' and toyuny desired extent to accomplish the feedin .Qitl ebeads, while the loo-per and sewing hook are subject to a universal inove'meut; Whiclrma'y be under hand con trol. feeder 'is subject to a universal feeding movement.

I have shewn' her'eiii a complete Serving machine embodying my invention in what I ondary shaft 4 which is operated from the main shaft by means of a belt 5 which travels over pulleys 6, 7, on the main and secondary shafts. The pulleys 6, 7, are provided with pins 8 which engage in apertures 9 in the belt so that there will be no relative slipping between the belt and pulleys.

The stitching member in the present case preferably consists of a needle or hook 10, and it is preferably arranged with its opcrating mechanism below the bed plate 2.

downwardly.- The string of The needle or hook 10 is carried by a reciprocating needle shaft 11 which is guided in journals 12, arranged below the bed 2; which shaft may be reciprocated and rotated in the journals. On the shaft 4 there is a disk 13 which has a pin 14 that travels in the groove of a cam block 15 (see Figs. 1, 6 and 7 in the grooves 16 of a supporting bracket 17 carried upon a depending standard 18. Carried on the cam block there is a sleeve 19 which surrounds the needle shaft 11 but is loose thereon to permit the needle shaft to revolve in the sleeve. Collars 20 are secured upon the needle shaft, and are arranged above and below the sleeve 19. As the shaft 4 revolves, the pin 14 which is arranged off the center of the shaft, will reciprocate the block 15 up and down, but not laterally, owing to the shape of the cam groove 2l. The reciprocation of the cam block will operate to reciprocate the needle shaft in its bearings, to cause the needle or sewing hook to perform its stitching operations.

- The looper for casting loops around the sewing hook or needle, is preferably arranged above the bed 2. The looper may be variously constructed, but I prefer to use a looper consisting of a threaded body 22 revolving freely in a supporting casing 23 and held in position by collars 24. In addition thereto the looper preferably consists of a tubular portion 25 extending outwardly and beads 26 travels downwardly through the looper and out of the tubular end 25 thereof. The looper body is free to rotate in its supporting casing; and in order to rotate the same there is a Worm or screw 27 arranged to reciprocate and also to revolve in the casing 23, at right angles to the looper body. The thread of the worm 27 meshes-with. the thread on. the looper body 22; and it is adapted to rotate The cam block 15 reciprocates the looper when'the worm 27 is reciprocated, or revolved, or when both reciprocated and revolved. The worm or screw 27 is carried upon a shaft 28 which is journaled in the machine frame and which may be reciprocated and revolved. One end of the shaft 28 is connected with one arm 29 of a lever which rocks on a fulcrum 30, by a connection which permits the shaft to revolve relatively to the arm. The other arm 31 of this lever is fulcrumed to a rod 32; and the latter is reciprocatcd by means of an eccentric 33 and strap 34. These connections serve toreciprocate the shaft 28 at each stitch operation of the machine, andthey permit a simultaneous rotative movement to be imparted to shaft 28.

To feed the fabric for the stitching operations I preferably employ a feeder and presser consisting of an annular ring 35 supported by an arm 36, over the bed 2, so as to encircle the path of the needle. The device which I prefer to employ for operating the feeder is as follows: A shaft 37 is supported over the sewing devices in brackets 38 connnecting with the head 39 of. the machine. Upon this shaft is ar.- ranged a sleeve 40 having a groove provided with a cam surface 41 (see Fig. 1).

The sleeve is loose on shaft 37 and it is adapted to reciprocate on-the same and to revolve around with it. A plate 42, sliding in a socket in the head of the machine frame, carries an arm 43 which partly encircles the sleeve 40 between the shoulders 44 thereof, whereby the sleeve 40 may revolve relatively to the plate 42 but is reciprocated by the latter. To the inner side of the frame head 39 is fulcrumed at 45, a

lever 46; and one arm 47 thereof engages with a cam 48 on the main shaft while the other arm 49 thereof cont-acts with a projection 50 on plate 42. Through the cam and lever the plate 42 and therefore sleeve 40 are periodically reciprocated; A sleeve 51 is secured to shaft 37; adapted to rotate with it, as will be explained later. It is provided with a pawl 52, one end of which engages the cam surface 41 of sleeve 40. The other end thereof operates against the action of a spring 53 to move the member 54 which surrounds a portion of sleeve 51 and which is secured to the arm 36 that carries the presser orfeeder 35. The member 40 is movable along the shaft 37 but both 40 and 51 are adapted to revolve with the latter. The arm 36 which carries the presser or feeder is fulcrumed to a block 55 and the latter is fulcrumed at 56 to a support 57; the fulcrums 55 and 56 being at right angles to each other, whereby the arm 36 ma be moved by the pawl 52 in any lateral direction. Traveling in a socket in the head 39 is another sliding plate 58 which carries the support '57 for Bill arm 62 in Contact with the cam 63. l /lien the shaft 3 is revolved, the feeder is moved up and down by moons of cam 63,

lever 62, 60 and plate 58. The cam 48, 1over 49 and plate 42 i'ei'ciprocote the sleeve 4.0, which causes the rocking of pawl 52 and lateral. movement of the arm 36..vl1icb carries the feeder. The direction of this lateral motion will depend upon the position of the sleeves l0 and 51, and that is con trolled by the hand feed device as will be hereinafter described.

In addition to the above parts 1 provides device for separating or feeding'tlic beads in proper order to the stitching devices; and I prefer to arrange the same between the lcoper and. the fabric so that the movement of the looper will coliperate therewith to. causethe separation or feeding of the beads. The device 01" this purpose is shown in detail in Figs. 8, 9, l0 and 11. An annular plate 66 is provided on its run with a gear 67. A bracket 68 is attached to extension of the frame and is formed-of separate halves 69 attached to the extension. The ring portions 70 thereof surround the plate 66 and engage in a gi oove 71 thereof. Zlhc put-pose of the bracket. 69 is to sup-port the separator in position over the fabric in a .manner which will permit the separator to be revolved-5 From the annular plate 66 extends inwardly a. neck portion 72 which carries a plate 73. The outer edge of the latter is preferably circular for a distance extending between, say, the points 74 and 75 and then turns inwardly between the points 75 and 76. On the under side of plate '73 is secured at the point 7.3 a tongue 77 which curves downwardly from the plate 78 a distance corresponding to the length of beads to be used in the machine. The tongue 77 preferably extends downwardly from the point where it is secured to the plate 73, an increasing distance. The outer edge of this tongue is preferably curved between the points 78. 75 in the some circle as the portion of the plate 73 between the points 74 and 75. so that the plate 73 and tongue 77 when viewed from above 01 below forn'i almost a complete circle. From the point. 75 the tongue curves inwardly to 79. Tliebeads are strung loosely on their thread and. the bead thread is fed in any desired ma-Imc-I' to and through the looper. It passes III the end 25 of the latter to the fabric Lb commencement of a stitch the end of the t i Will be in position near the point 7% ti e oarator; and the lowermost head on 1 thread will lie against the top sur- -e of plate Upon a partial revolution 01 the looper, the bead thread will be carried around the edge of plate 73 with the thread in Contact with the edge thereof and the beads resting on the plate. When the loogicr has revolved part way around the bead thread will loose conlact with the edge of plate 73 at about the point 75; and it will eomnieue to contact with the edge of the tongue. When this occurs, the beads will move down on their thread until the lowermost one rests on the tongue 77 which is at a slightly lower level to plate 73. The looper ill reach its extreme movement, in this direction when the thread is in contact with the tongue or near the neck 72. Just previous to the above movement of the loopeithe needle or boolz 10 was advanced through the fabric by means of the crank,

pin and cam block previously described. The looper therefore, in carrying the thread around the separator also casts a loop of the thread around the needle, the needle or book at that time extending through the fabric and the aperture 73 in plate 73. The

needle will then immediately descend and its book will carry the thread through the fabric, forming a stitch therein, with the head thread. At about this time the looper will be reversed in direction. It will now carry the head thread around the separator in a reverse direction to the first movement. The lowermost bead rests on the tongue 77 durii s a. rtion of the return movement on til the thread comes to about the point 7 5. Then the thread will change from contact with the tongue to contact with the plate 73. The plate 73 will now come between the lowerii'iost bead which was resting on the tongue, and the one above it. Upon continuation of the movement of the looper, the lowermost bead will ride oil the tongue, and fall down its thread to the fabric where the last stitch was stormed. The head above it, which was the second bead, now rests on the plate 73; while the thread contacts with the outer edge thereof. The looper will reach the extreme of its return movement near the point i'e This completes one stitching operation. The same operations will be repeated; and each time the looper oscillates baclc and forth around the separator it will not only cost the loop around the needle or sewing book, butit will cause a bead to be separated from those above it and to drop down to the fabric, The needle or hook, will therefore form stitches with the bead thread, between the several beads. While the needle is in she 'tabric, the presser or feeder 35 will be pressed upon the fabric by the action of the spring 65. WVhen the needle moves out of the fabric, the feeder 35 will be moved laterally by the action of cam 48, lever 49, plate 42. sleeve 40 and pawl 52. As soon as ther lateral feed has taken place, the presscr will be raised by cam 63, lever 60, ctc.,'and after rising the feeder will be moved back idly and then down upon the fabric for a second feeding operation.

I provide means for operating the presser or feeder, in any desired direction and to position the looper, the needle, and the separator, whereby a fabric may be obtained, in order to secure the string of beads to the fabric in any desired direction. I provide a hand control for operating the above in synchronism, whereby there will be no conflict in the operation of the several devices.

A vertical shaft 80 is provided with a hand crank 81 for turning it. On this shaft there is a miter gear 82 meshing with a miter gear 83 on a shaft 84. The latter also has a miter 85 which meshes with a miter gear 86 on the needle shaft 11. The latter gear is connected to the needle shaft by a feather so that the needle shaft may be reciprocated. The turnin of the crank 81 Wlll operate through s aft 80, gears 82, 83, shaft Set and gears 85, 86, to revolve the needle shaft according to. the direction in which the fabric is to be fed or stitched. On the shaft 80 there is a miter gear 8'? which meshes with a miter gear 88 on a shaft 89. The latter has a miter gear 90 which meshes with the ear teeth. 67 on the separator or bead fee er. When the crank 81 is operated to turn the needle shaft, the gears 87, 88, shaft 89 and gears 90, 67 will also operate to revolve the separator in accordance with the direction of feed of'the fabric. Onthe shaft there is a miter gear 91 which meshes with a miter gear 92 on shaft 28 which operates the looper. When the crank 81 is operated to turn the needle shaft and separator, the gears 91, 92, will also cause the shaft 28 to revolve, This will revolve the looper and the action mav be simultaneous with the movement imparted to the looperby the reciprocation of the shaft 28. The gear 92 is connected with shaft 28 by a feather so that the shaft may be reciprocated relatively to the gear, but be turned by the latter.' On the upper end of shaft 80 there is a miter gear 93 which meshes gear 94 on a shaft 95. There IS a miter gear 96 on the latter, whichmeshes with a miter gear 97 on shaft 37 When the'crank 81 is turned, the shaft 80', gears 93, '94,

shaft and gears 96, 97, will revolve shaft 37 and with the latter the revolve. Thus the pawl 52 will be brought universal feeding of thewith a miter sleeves 40, 51. willto any desired position to operate the arm 36 and feeder 35 in any desired lateral direction; to cause the fabric which is being stitched to be fed in any desired direction.

-From the. above it will be ap arent that the various sewing devices, inc uding the bead separator or feeder, may be turned in the desired direction and to any desired extent to cause the beads to be sewed to the fabric straight, curved or angular, or any variation thereof. All the devices are turned synchronously, so that they will always properly cooperate regardless of the direction of feed of the fabric. Various changes in'the mechanism and the positions of the various devices may be made without departing from the spirit and scope of my invention.
